DRAFT-REGULATING DEVICE FOR PLOVVS AND CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 387,689, dated August14, 1888,

Serial No. 255,918. (No model.)

.To all whom it may concern:

Be it known that I, ADIN LYON, a citizen of the United States, residingat Spring Hill, in the county of Bradford and State of Pennsylvania,have invented certain new and useful Improvements in Draft-RegulatingDevices for Flows and other Implements to which it is Adapted; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My improvement relates in particular to draft attachments for plows, butmay be applied to harrows,wagons, reapers, or any other implements inwhich it is desired to change the point of application of the draft; andit consists in a draft-piece made adjustable vertically in guides madeinor fastened upon the beam of the plow or some similar part of the otherimplements. This draft-piece is raised and lowered by a ratchet-leverand has connected to it and adjustable with it a roller or wheel.

Figure 1- is a side View of a plow with my invention applied; Fig. 2, anend View of same; Fig. 3, a section on line as a: of Fig. 1; Fig. 4, aside view of part of solid metal beam with slot in end; Fig. 5, a sideView of a modification; Fig. 6, a section thereof on line 3 3 The beam Ahas upon its end the piece B, which has the two arms 11 b, closelyembracing the end of the beam, and by means of which the piece B isbolted or otherwise securely fastened to the beam A. This guide-piecehasin the end a slot which in cross-section is T- shaped. It is also asegment of a circle with its center at or near the pivotal point of thelever L. The adj usting-leverL is pivoted upon the guide-piece B, or thebeam, as is most convenient, and extends back to a point where it can beconveniently operated. Fastened to the beam is a rack-bar, P, havingteeth to be engaged by a sliding lock-bolt, Z, sliding in guides uponthe lever L. This bolt is thrown into engagement by an ordinary verticalspring which surrounds it, or is otherwise spring-actuated. It iswithdrawn from engagement by a trigger, t, pivoted upon the handle andconnected to the bolt by a rod or wire, w.

The draft-piece,or piece to which thcpower is directly applied, is incross section T-shaped to fit the slot in the guide-piece B. The flangesare also of the same curvatureas the slot. The web (2 has holes h h forthe attachment of the clevis through which the draft is applied. Thisweb d extends far enough forward that the clevis will freely clear theend of the piece B. Pivoted at one end to the draft-piece D andadjustable vertically with it are the curved bars 6, which at the otherend are pivoted to the beam. These bars carry the wheel B.

The construction of parts described is the one I prefer; but it may bevaried somewhat and yet be essentially the same. For instance, the beammay be of iron and have the guideslot formed in the end, thus dispensingwith the separate guide-piece B. The rack-bar B may be placed upon theother side of the fulcrum, as shown in Fig. 5, which illustrates anotherform of construction. In this form the guide-flanges are upon the end ofthebeam, and the draft-piece B has a T-slot which embraces theguide-fianges, thus forming a sort of cap. The rackbar It is alsolocated upon the beam between the fulcrum and the adjustable guide-pieceB. The curved bar 0, earrying the wheel R, is also attached directly tothe lower'part of the draft-piece D, instead of to the upper part, as inFigs. 1 and 2. Upon the front face of the guide-piece D is a horizontallug or flange, g, which has a number of holes in it for the attachmentof the draft clevis, so that the draft can be regulated horizontally aswell as vertically.

It will be observed that the colter and draft attachment aresimultaneously adjustable, so that when the draft-piece is raised orlowered the colter is by the same means and movement likewise raised orlowered.

It is obvious that changes can be made without departing from the spiritof my invention.

Having described my invention, what I claim, and desire to cover byLetters Patent, 1s-

1. In a draftregulating device, the guidepiece B, draft-piece D,vertically adjustable in said guide-piece B, and adjusting-lever L, incombination with devices for securing said lever L at any point, thebars 0, connected to and moving with the draft-piece D,and wheel R,substantially as described.

2. In a draft-regulating device, the guidepiece 13, draft-piece D, oneof said pieces hav ing a T-slot and the other flanges to fit said slot,whereby vertical adj nstment may be obtained, ad jnsting-levcr L,devices for securing said lever at any point, in combination with thebars 0, connected to and moving with the draft-piece D, and wheel R,substantially as described.

3. In a draft-regulating device, the guide- ])lCCO B, draftpiece I), oneof said pieces havin a T-slot and the other flanges to fit said slot,whereby vertical adjustment may be obtained, in combination with the adjListinglever L, rack-bar I, lock-bolt 1, spring for returning the same,trigger 1 and connectingrod 20, bars 0, secured to and moving with thedraftpiece 1'), and wheel it, carried by said bars, substantially asdescribed.

In testimony whereof I alllx my signature in presence of two witnesses.

ADIN LYON.
